The normal weight of a child c. Features of the ratio of height and weight in adolescents. Stages of growth in children

Height and weight of the child are the main indicators of its physical development. That is why immediately after the birth of the baby, it is imperative to measure the weight of his body and the length of the body and continue to weigh himself daily at the same time until discharge from the hospital.

There are many factors that affect the physical development of a child, for example:

• heredity (do not expect a son-basketball player from short parents)
• nutrition (it's no secret that with a deficiency of nutrients, vitamins and minerals, the growth and development of the child slows down)
• physical activity (for example, playing tennis, volleyball, basketball contribute to an increase in height)
• child health (children with chronic diseases often lag behind their peers in physical development)
• psychological situation in the family, at school, lack of sleep, etc.

How to understand what is the norm?

All-Russian Health Organization recommended special tables for matching the height and weight of children, or as they are called, centile tables. At each examination, the pediatrician measures the height and weight of the child, compares the obtained values ​​\u200b\u200bwith the standard indicators. Such tables allow you to identify obvious pathologies, for a more accurate analysis, the doctor calculates additional indicators using special formulas.

Deviations of weight or height from tabular values

There is no need to panic at the minimum discrepancy with the indicated values ​​in the table, and here's why:

1. First of all, tables of height and weight of the child contain benchmarks, then what should ideally be the weight and height of the child, without taking into account many other factors. Sometimes parents of premature babies mistakenly use a standard table for comparison, while there are special tables for assessing the development of children born prematurely.
2. The rate of growth and weight gain is unique for each child.. In the first year of life, babies develop in leaps and bounds. For example, during the period of introducing complementary foods, the weight of the baby may not reach the “norm” due to adaptation to a new type of food, and not because of pathology.

This does not mean that deviations from the norm should be ignored., but it is better to regard them as an occasion to pay attention and consult with a specialist in order to identify possible health problems, or make sure that they are not.

What can be associated with obvious deviations from the norm?

Earlier we talked about minor deviations from the norm and that there is no need to be scared if your child grows and gains weight not strictly according to the table. But what to do if the values ​​of the essential are out of range of acceptable parameters or are they at the intersection of norm and pathology?

The reasons for possible deviations can be divided into two groups:

1. Non-endocrine:

• Constitutional stunting. Or in another way, the syndrome of late puberty. One of the variants of the norm, when the puberty jump occurs later than in other children.
• family short stature. It has a hereditary predisposition, in the family of such children there are relatives with short stature. Growth retardation manifests itself from early childhood.
• Prematurity, intrauterine and postpartum trauma.
• Genetic Syndromes. As a rule, they have many clinical manifestations, one of which is growth retardation.
• chronic diseases cardiovascular, bronchopulmonary systems, gastrointestinal tract, as well as anemia.
• Starvation.
• Taking certain medications.

2. Endocrine:

• Growth hormone deficiency. Biologically active substance, which is the main regulator of the growth process after 2 years.
• Lack of thyroid hormones. More often of a congenital nature, it is clinically characterized by a delay in physical and intellectual development from birth.
• Type 1 diabetes. A disease in which, due to insulin deficiency, the flow of glucose into the cells of the body is impaired, the so-called. "starvation" of cells, as a result, growth rates slow down.
• Cushing's disease (or syndrome). At the same time, the production of hormones of the adrenal cortex, glucocorticoids, is increased, which in large doses leads to a violation of the secretion of growth hormone.
• Rickets. A lack of vitamin D leads to bone destruction and skeletal deformities, which in turn is manifested, among other things, by a decrease in growth.
• Other rare disorders of the endocrine system.

As you can see, there are many reasons.

If the growth of the child is stunted, parents should consult a doctor to identify the causes of short stature and its timely correction.

Remember that for the normal growth of the child, you need a complete, balanced diet with enough vitamins and minerals, as well as dosed physical activity.

At the pediatrician's appointment, each baby up to a year is weighed monthly and measured for height. Why is it so important for doctors to know how a child is growing and how much he is gaining weight? What do these parameters say, and what are the anthropometric norms for children of different ages?

Where did the weight and height indicators for children come from and why are they needed?

Anthropometric data of a child are one of the main indicators of the physical development and health of children. Significant deviations from the normal values ​​​​of height and weight in a child almost always indicate the development or presence of certain diseases. So, if a child under one year old with adequate nutrition does not gain weight well, then this may be one of the symptoms of rickets, anemia, immunodeficiency states, diseases of the endocrine or central nervous systems.

A significant growth retardation may indicate a lack of somatotropin growth hormone in the body, and a clear excess weight with normal growth and proper nutrition may indicate disorders in the adrenal glands, thyroid gland, and even the development of a brain tumor.

In order to detect and start treating such formidable diseases in time, doctors carefully monitor the anthropometric indicators of children from birth. Development standards are compiled by the World Health Organization on the basis of many years of research. In addition to the average standard indicator for each age, the limits of the norms were also calculated. Weight and height above this limit is considered high, and below - low. It is for such children that doctors begin to observe especially closely.

WHO table of height and weight for girls under 1 year old

According to the norms, a healthy full-term girl is born with a height of 49.2 cm and weighs 3.200 g. This is the average. The lower limit of the norm for a newborn is a height of 47.3 cm and a weight of 2.800 g, and the upper limit is located at values ​​of 51 cm and 3.700 g, respectively. Values ​​outside the lower and upper limits of the norm are marked as very low or too high. Doctors will observe such a newborn and, possibly, additionally examine it.

During the first month, the newborn should grow by 4.5 cm and gain a kilogram. The lower limits of the norm for a monthly girl will be 51.7 (height in cm) //3.600 (weight in grams), and the upper limits - 55.6 //4.800.

Normal indicators for a two-month-old baby: 57.1 cm and 5.100 gr. The lower limit of the norm is 55//4.500, and the upper limit is 59.1//5.800.

By three months, girls grow to 59.8 cm and weigh 5.900 grams. Low for a three-month-old baby is considered to be less than 57.7//5.200, and high is more than 61.9//6.600.

A ten-month-old baby, according to the norms, should be 71.5 cm tall and weigh 8.500 grams. The lower limits of the norm for ten months are 69//7.500, and the upper frames: 74//9.600.

By eleven months, a normal girl grows to 72.8 cm and weighs 8.700 grams. Indicators less than 70.3//7.700 are considered low. High will be indicators exceeding 75.3//9.900.

By the year, according to the norms, girls should grow up to 74 cm and weigh 9,000 grams. The parameters 71.4 //7.900 are considered the lower limit of the norm, and 76.6 //10.100 are considered the upper limit.

WHO table height and weightfor boys up to 1 year

The norms for boys are different from the norms for girls, as boys are usually born slightly larger. So, a healthy full-term newborn boy is usually born with a weight of 3.300 grams and a height of 49.9 cm. These figures are considered normal. The lower limit of the norm for a newborn is a height of 48 cm and a weight of 2.900 g, and the upper limit is at 51.75 cm and 3.900 g, respectively.

For the first month, the baby should grow by 4.8 cm, and gain 1200 gr. The lower limits for a monthly boy will be 52.8 (height in cm) // 3.900 (weight in grams), and the upper limits - 56.7 // 5.100.

Average height and weight for sixteen-year-old girls: 162.4 / / 56.5. Lower limit: 155.2//48.4, upper - 170.2//67.6.

For girls at the age of 17, the standard is 163.9//61. Lower limit: 155.8//52.8, upper: 170.5//68.

Table of height and weight for teenage boys

Boys between the ages of 10 and 14 years are slightly behind girls in growth, this is normal, since hormonal changes in boys begin a little later than in girls. But after fourteen years, guys begin to grow more intensively than girls, and by the age of 15 they overtake them in terms of growth.

In adolescence, anthropometric indicators significantly depend on genetic predisposition, therefore, when monitoring the physical development of adolescents, it is recommended to focus not so much on the average, but on the limits of the norm indicated for each age and on the child's heredity. So, if the father of a young man has a height of 190 cm, then the height of 182 cm of the teenager himself at the age of 15 can be considered the norm in this case.

For an 11-year-old boy, the average figures are: 143.5 (height in centimeters) / / 35.5 (weight in kilograms). Parameters less than 134.5//28 are the lower limits of the norm, and parameters greater than 153//44.9 are the upper limits.

Average height and weight for a twelve-year-old teenager: 149 / / 39.8. From the border: 140//30.7, to: 159.6//50.6.

A thirteen-year-old teenager normally has the following indicators: 155.5//44.3. From the border: 145.7//33.9, to: 166//59.

At the age of 14, the average indicators are 161.9//49.7. From the border: 152.3//38, to: 172//63.4.

By the age of fifteen, the average height of the guys is 168 cm, and the weight is 55.5 kg. From the border: 158.6//43, to: 177.6//70.

Average height and weight for sixteen-year-old boys: 172.3 / / 66.9. From the border: 163.2//48.4, to 182//76.5.

At seventeen, the average height and weight are 176.6 / / 66.9. From the border: 166.7//54.6, to: 186//80.1.

Video "The height and weight of the child, Dr. Komarovsky"

The neighbor's boy Vanya is almost half a head taller than my six-year-old son, despite the fact that they are the same age. But my teenage daughter is the opposite - she is the tallest in the class among girls. What if the son will remain short, and the daughter will grow more and more?

Like any mother who worries about the future of her child, such questions haunt me. Of course, appearance is not the main thing, but still, you don’t want them to say about your child later “a good guy, but he didn’t come out tall.” Does the growth correspond to the age of the child, and what factors can influence these indicators?

Matching the height and age of the child. All children "one size fits all".

It is known that arithmetic mean values ​​are used to create any anthropometry table. From this it should be concluded that not all children can "fit" into the obtained values. And does this mean that this child does not correspond in size to his age? Yes, but only in tabular values.

Despite this, all pediatricians and parents want the baby to at least keep up with the generally accepted norms in physical development. Naturally, the minimum discrepancy between the height and age of the baby will not play a big role, however, it is the comparison of his anthropometric data with tabular norms that helps to assess physical development.

Correspondence of the height and age of the child: jumps "up".

In certain age periods, intensive growth in children is noted. A child can "stretch out" in a matter of months. Usually mothers notice this by his clothes, which become small. Fast growing children are usually seen:

• At the age of three;
• At the age of seven;
• At 10 years old, more often in girls;
• At 13-15 years old, more often in boys;

Matching the height and age of the child. What factors affect this?

hereditary factor.

(Dad's height + mother's height) / 2 = x + 5 cm (for boys) or x-5 cm (for girls). In this way, you can calculate the approximate height of your "adult" child. According to such calculations, if the mother is 160 cm tall and the father is 190 cm tall, the estimated height of the matured child will be about 175 cm. However, such a simple formula does not take into account the gender of the child, the dominance of the father's or mother's genes, therefore it is used extremely rarely.

Nutrition.

The correspondence between the growth and age of the child largely depends on the quality of nutrition. The lack of minerals and trace elements necessary for growth and development can play a cruel joke. With insufficient intake of fats and proteins, the body simply does not have the ability to synthesize hormones, build new cells, develop and grow. That is why it is so important that your child eat regularly and in a balanced way.

Hormonal background.

Thyroid diseases, diabetes mellitus, precocious puberty also affect the growth of the child.

Quality and duration of sleep;

Physical and psycho-emotional stress;

Psychological situation at home;

Intrauterine developmental delay (with complicated pregnancy);

Chromosomal abnormalities.

Matching the height and age of the child. We take correct measurements.

Before you ask the question about the appropriateness of growth for the age of the child, you need to learn how to measure it.

Children up to a year are measured with a centimeter tape in the prone position. For this baby, you can put it on the table, gently straighten the baby's knees and take a measurement.

Older children are measured using a height meter in the clinic or a homemade paper height meter that is pre-attached to the wall. The feet of your child should be tightly shifted together, arms along the body in a free position, knees unbent and relaxed. When taking measurements, the child should touch the wall at three points: shoulder blades, buttocks, feet. For the most accurate measurement, a flat object should be applied to the top of the child's head in a perpendicular direction.

If the growth of the child does not correspond to age - do not take this news to heart. Surround your baby with care and love, create conditions for his physical and creative development and enjoy every day spent together. Childhood is fleeting, you will not notice how quickly your children will grow up and become big and adults.

Immediately after the birth of the baby, happy relatives are informed of the main parameters of his body - height and weight. Norms of weight and height in children - the table provides data not only for infants under one year old, but also for older children.

This is very convenient for parents, especially if they tend to worry about the rapid growth, severe thinness or fullness of their crumbs.

It is the height and weight of the child by age that are important for both parents and doctors. The ratio of height and weight in children is individual, depending on the genetic predisposition and other factors.

But children under 1 year old, according to statistics, have approximately the same anthropometric indicators. Such data indicate that the baby is developing and eating properly.

Excessive thinness, or vice versa, swelling, indicate an improper diet for the baby or a predisposition to such addition. Although a chubby rosy-cheeked baby is tender, it’s still not worth overfeeding children. Extra pounds in early childhood complicate the functioning of the heart and blood vessels and can slow down the physical development of the crumbs.

For children, there is no universal formula for determining the norm of body weight. To calculate the exact rate of growth and weight of girls and boys up to a year by months, there are so-called "centile tables".

The table is compiled by scientists based on measurements of the height and weight of children of different ages and a wide variety of builds. Then, with the help of centile tables, it is easier for pediatricians to determine whether the child is developing normally.

What is this table? For clarity, here is an example:

Imagine that one hundred children were lined up according to their height. Those guys who will be closer to the center are considered “normal”, those who are tall at the beginning of the line will be called “tall”, and the last smallest will be defined as “short”.

Thus, there are children with normal or average development in height and weight, but there are also those who grow and gain weight above or below the average. Therefore, parents should not be very worried if the height or weight of their baby deviates slightly from the generally accepted norm.

The centile table gives approximate values ​​for height and weight. Deviations from this norm do not mean any pathology at all, but you should still observe the development of the child and his health.

The weight norm for a child up to 12 months is calculated based on growth rates within the limits determined by the World Health Organization for infants.

The norms established in the table help to comprehensively assess the weight of the baby in exact accordance with his age and height. The resulting ranges of values ​​are compiled by WHO - the World Health Organization, which were obtained during the study of the development of healthy children in different countries.

After the birth of children, be sure to weigh and measure the length of the body. This is necessary in order to observe the increase in grams and centimeters. Then the young mother should regularly visit the district pediatrician every month to record and monitor the dynamics of the developmental indicators of the baby.

The following data are considered the norm for newborns - height 45 - 60 centimeters, 2300 - 4500 grams. Each child's height and weight are affected by different factors.

So, the growth of the baby may differ from the norm depending on the course of pregnancy, as well as on genetic data. If during pregnancy the mother did not adhere to a healthy lifestyle or the baby did not have enough air in the womb, then the length of the baby's body can be significantly less.

And the nutrition of the expectant mother has a great influence on these weights. When eating more high-calorie foods, the likelihood of having a baby with overweight increases.

It is interesting that in the first day the newborn loses up to 10% of the norm in weight, but then, with proper nutrition, he will gain the prescribed grams.

During the first year, children gain up to 8 kg in weight and grow by about 24 cm. During the first three to four months, weight is added by 600 - 800 grams. But then the children begin an active lifestyle, which requires a lot of energy, so the increase is almost halved.

If we talk about how to measure height, then babies up to two years old are measured in a lying position, and older children in a standing position. In this case, there can be a difference of up to one centimeter between body length and height.

Weight height age - newborn baby table

This table shows the ranges of values ​​for the weight and length of the body of newborns, corresponding to the norm. BMI is a body mass index that shows the relationship between height and weight. BMI helps to objectively determine the presence of problems associated with the development of the baby.

Below is a table of average anthropometric data for children under one year of age. Changes in the weight of the baby approximately correspond to the following standards:

• in the first days of life, body weight decreases by 5-10%;
• in the first month, the daily increase is about 20 grams;
• in the second month, the baby should recover by 25-30 grams per day;
• within six months, the weight doubles from the original;
• in a year of life, a child should gain about 3 times more weight.

If we talk about the growth of a newborn, then here the norm is more stable than weight - the growth of the baby increases by an average of 3-4 cm every month.

Another indicator that the district pediatrician controls is the measurement of the circumference of the head and chest. In newborns, the circumference of the head is larger than the volume of the chest by about 3-5 centimeters. Then the circumference of the chest increases much faster and ahead of the head. In this case, it is not so much the numbers that are important, but the dynamics of their change.

Also, the norm of the weight of a child up to 12 months can be calculated using the following formulas:
1. For children under 6 months: Birth weight + 800 - M = body weight, where M is the number of months.
2. For children from 6 months to 1 year: Birth weight + 800x6 + 400x(M-6) = body weight, where M is the number of months from 6 to 12.

WHO height and weight of the child - what indicators depend on

Although any deviations in the development of the baby from the above norm may disturb parents, this is not always a reason for panic. A number of factors should be taken into account that can affect the main parameters of the length of the body and weight gain of the child.

Let's consider some of these factors:

• Heredity. Basically, the body weight of a newborn is determined by genetics. In overweight parents, most likely the baby will not be thin.
• Gender identity. Girls are often smaller and smaller than boys.
• Appetite. Each child has its own characteristics, in particular - a good or poor appetite.
• Health status. If children are ill with something, this will also affect their appetite.
• Mother's health status. If during pregnancy or lactation a woman has suffered any illness or nervous stress, this can affect the baby's body weight.
• Maternal nutrition during pregnancy and lactation. If a woman consumed a large amount of high-calorie foods, then there is a high probability of having an overweight baby and vice versa.
• type of feeding. Formula-fed babies often gain weight slightly faster than breastfed babies. Also, in children who are fed on demand, and not on a schedule, weight and height gains are more stable.

The percentage of overweight children worldwide is increasing at an alarming rate - on average, one in three adolescents or children are now overweight or obese.

Now many children spend little time on training and outdoor games, they spend more time in front of the TV, playing video games or the computer. And in many working, busy families, parents have less free time to prepare healthy, home-cooked meals. From fast food to the computer, fast and in a hurry is the reality for many families.

Keeping children from being overweight means establishing the right diet and sports in the family, as well as useful rest together. We must include our children in a healthy lifestyle by our own example.

Is your child underweight or overweight?

The World Health Organization (WHO), the US Department of Health, and most countries around the world successfully use BMI - body mass index - which is based on the ratio of height and weight, and the subsequent calculation of the percentage of fat in the human body to assess excess weight in adults and children. The BMI calculation method is the development of Adolf Quetelet and for children it provides a special scheme. First you need to calculate the BMI of the child according to the general formula:

Body mass index (BMI) calculator using the Quetelet formula

Since children and adolescents are characterized by active growth and development, their BMI can change significantly over a short period of time. Therefore, the usual assessment of BMI, common in adults, is not suitable for them. In order to accurately and correctly estimate the body mass index of a child, scientists examined the ratio of mass and height of many thousands of children. And when it comes to determining whether your child's BMI is normal or out of range, comparison tables - "percentage curves", or distribution scales - with averages for children of this age and height will give you the opportunity to understand whether weight needs to be adjusted. In this way, your child's body mass index is compared to the average of thousands of other children. This approach takes into account the developmental stages that children go through in certain age groups. For example, if a child has a body mass index higher than 97% of children of the same age, then it can be concluded that the child is overweight.
This table contains information on the BMI of adolescents and children of both sexes from 2 to 20 years.

As a result, your child's BMI will fall into one of four categories:

• Lack of weight: BMI below the 5th average (percentage curve);
• healthy weight: BMI between 5th and 85th average;
• Overweight: BMI between 85 and 95;
• Obesity: BMI is in the region of 95 or higher.

For children under 2 years of age, doctors use weight-for-height charts and a thorough physical examination.

Table for estimating the weight and height of a child by BMI

At the same time, BMI is not an ideal indicator of the amount of body fat and can be misleading in some cases. For example, a heavily muscled teenager can have a high BMI without being overweight (muscle is added to body weight, not overweight). In addition, BMI can be difficult to estimate correctly during puberty, during which young people go through stages of rapid growth. In any case, it's important to remember that BMI is generally a good indicator, but it's not a direct measurement of body fat.

To establish the exact percentage of adipose tissue allows bioimpedance analysis. With the help of a certain device, a weak, safe electric current is passed through the body, changing its frequency. Different tissues of the body have different resistance to electric current, thus, it becomes possible to calculate what proportion of the body is muscle, and what proportion is bone and fat.

If you are concerned that your child may be overweight or underweight, arrange an appointment with your primary care physician who will evaluate your diet and physical activity levels and suggest positive changes. Your doctor may also recommend prevention for certain conditions associated with being underweight or obese.

Prevention of overweight and obesity

The key to keeping kids of all ages at a healthy weight is lifestyle for the whole family. This is what is "preached" in the family. Make physical activity and healthy eating a family hobby. To make it fun for the kids too, let them help plan healthy menus and prepare meals, and take them to the grocery store so they learn how to choose healthy and healthy foods.
Don't fall into these common nutrition traps:

• Do not reward children for good behavior or try to keep them from bad behavior with sweets or treats. Encouragement or punishment should not include food, there are many other effective and correct ways of education.
• Don't Support the "Clean Plate Policy". Watch for signs that your child is hungry. Even babies who turn away from a bottle or breast report that they are full. If the children are full, do not force them to continue eating. Remind ourselves that we should only eat when we are hungry.
• Don't talk about "unhealthy foods" and don't completely eliminate all sweets and favorite treats from the children's menu. Children are more likely to rebel and eat large amounts of these unhealthy foods outside the home or when their parents are not watching.

conclusions

It is not easy to motivate a child for a result, he cannot be “put” on a diet. In turn, adolescence is complicated by the fact that there is a danger of self-rejection, isolation, depression, anorexia. Once you've figured out if your child needs weight management, we'd like to make some additional recommendations for kids of all ages:

• From birth to 1 year: In addition to the well-known health benefits, breastfeeding can help prevent excessive weight gain as well. And although the exact mechanism has not yet been established, breastfed babies feel their hunger and satiety more clearly, thus protecting themselves from overeating.
• From 1 year to 5 years: It is better to develop good habits from an early age. Help your child establish healthy eating habits by offering a variety of healthy foods. Encourage the child's natural inclination to activity and help him develop.
• 6 to 12 years old: Keep your child physically active every day. Let it be a sports section or outdoor games in the yard. Encourage activity at home - in everyday housework and in joint games and walks on weekends. Teach your child to choose healthy and healthy foods, help him pack his own sandwiches for school.
• 13 to 18 years old: Teenagers often lean towards fast food, but try to encourage them to eat healthier. For example, sandwiches with baked chicken meat, salads and smaller portions. Teach them how to cook delicious healthy meals and treats at home. Help them maintain physical activity every day.
• All ages: Reduce the amount of time your child spends in front of the TV, computer and playing video games. Fight your child's habit of eating by watching TV or a computer monitor. Try to prepare and offer your child a variety of healthy foods. Try to have breakfast, lunch and dinner with your child together. Encourage children to eat vegetables and fruits at least five times a day, limit sugary drinks, and never skip breakfast.

By eating right, exercising frequently, and incorporating healthy habits into your family's normal daily routine, you are building a healthy lifestyle for your children that they can continue to maintain. Explain to them the importance of physical activity and proper nutrition, but be sure to make it a shared family habit so that it becomes second nature to each of you.

But above all, let your children know that you love them regardless of their weight, and your main desire is to help them be happy and healthy.
